RADIATOR;

SPECIFICATION forming part of Letters Patent No. 623,609, dated April 25, 1899. Applicatio fil d December 27,1898. Serial No- 700,4:07. N0 model.)

To ttZZ whom, it may concern:

Be it known that 1, JOHN WILLIAM LANG, manufacturer, of the city of Toronto, in the county of York and Province of Ontario, Can ada, have invented certain new and useful Improvements in Radiators, of which the following is a specification.

The object of my invention is to devise means for producing a complete circulation of steam or hot water in a radiator without increasing the cost of the same;. and it consists, essentially, in closing the connections between the radiator-sections alternately at the top and bottom by means of removable diaphragms preferably forming part of the connecting-nipples, substantially as hereinafter more specifically described and then definitely claimed.

Figure lis a sectional end elevation of a radiator provided with my improvements. Fig. 2 is a vertical longitudinal section of the same. Fig. 3 is a perspective detail of a threaded nipple. Fig. 4 is a longitudinal section of a plain nipple.

In the drawings like letters of reference indicate corresponding parts in the different figures.

A A are the radiator-sections. In the drawings these sections are shown with two loops; but it will be understood that any number of loops may be used in each section.

B B are the connections, with openings formed therein, by means of which the radiator-sections communicate with one another. These sections are drawn together by various means, one being the right and left hand threaded nipple 0, (shown in Fig. 3,) which engages with corresponding threads out in the connections, or else plain nipples, such as shown in Fig. 4, may be used, in which case it is necessary to use independent means for drawing the connections together to make tight joint-s.

Ordinarily all the nipples in the radiator are entirely open, so that steam entering into the bottom of the radiator at one side may rush right through the connections and out 'would be two of these diaphragms at the bottom and one at the top, andthe steam is compelled to traverse every section in turn. All

diaphragms at the top of the radiator are preferably provided with air-vents a, so that all air in the radiator may be drawn out by placing a suitable valve or air-outlet close to the top of any given section. Such air-valves are commonly used and need no description or illustration. All diaphragms at the bottom of the sections are preferably provided with water-passages b to provide a free escape for condensed water from the bottoms of the radiator-sections.

In the screw-nipple the diaphragm is preferably cast integral therewith,and in the plain stamped nipple (shown in Fig. 4) the diaphragm is, placed in a piece of straight tube, which is afterward pressed in a die to give its ends the taper shown and to cause it to firmly and securely embrace the diaphragm.

From the construction described it will be seen that I have devised very efficient means for producing a complete circulation of steam in a radiator at little or no increase of cost over the ordinary plain radiator. My radiator will also be found to be more economical, as the complete circulation of the steam enables a smaller number of sections to do the work, as there is no possibility of the ends becoming cold through insufficient circulation or pocketing of air, as frequently occurs in Ordinary radiators.

What I claim as my invention is 1. A radiator comprising two or more sections, in combination. with removable diaphragms located in the connections between the sections alternately at the top and bottom of the radiator, air-vents being formed in the upper diaphragms and water-passages rd through the lower, substantially as and for the purpose specified.
